The plunger is normally extended by light spring force. When the workpiece is loaded, its weight depresses the plunger to the proper height. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely. Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process.
Mounting & Fluid Supply
Several possible mounting methods: 1) insert two socket-head cap screws from the plunger end, through the two counterbored holes parallel to the plunger; 2) insert two socket-head cap screws from the bottom end, through the two counterbored holes parallel to the plunger; 3) insert two socket-head cap screws through the two broad-side holes perpendicular to the plunger. 1/4″ BSPP port. For optional manifold mounting, use either the manifold port at the bottom end or the manifold port on the broad side by unscrewing the sealing plug and installing a CLR-3000-347-SW O-ring (also install a CLR-810-F Port Plug in the 1/4″ BSPP port). Do not use NPT fittings.

Block-type Work Supports are easy to mount horizontally, as in this example of a slitting operation.
